There is really only 1 way to install the Realtek HD Audio drivers properly. No matter what all other forums say. Service Pack 3 is the main culprit as the drivers see that its above SP2 and dont install. I personally face this situation and was really distressed because it looked like either i will have to reinstall Windows Xp or have my new supercool and super monster computer without sound. Imagine having a monster PC with a motherboard with HD Audio and your driver doesnt install.

Both scenarios were something which i would never have approved of. Anyway so i Googled. I got 10s of solutions but most didnt work. Only 1 worked and i will put it here hoping that Google dear will catch it and people who face this problem installing the Realtek HD Audio 0xE000027.

  1. First Step is to make sure all instances Realtek Audio and its associative softwares are uninstalled from add remove programs and device manager. This includes Intel High Definition audio.
  2. On your PC change the CSDVersion registry key to Windows XP SP2:
    HKLM\SYSTEM\CurrentControlSet\Control\Windows\CSDVersion value=200

This problem arises as the patch thinks that SP3 includes a better version of the patch itself and hence doesn’t install itself.

3. Download the latest drivers from the Intel website, navigate to the KB888111 patch.

4. But before installing the patch, goto your device manager and disable the UAA. Now uninstall the UAA.

5. Install your patch now.

6. Install the Realtek drivers now and things should work.

7. Change the SP version to 300 again.

If it didnt work, try once again. I can enjoy 7.1 channel high definition sound from my Intel Original motherboard now. Realtek HD Audio now works fine. Hopefully Error 0xE000027 is fixed now.

    Monster PC, LOL…

  2. Ravi Says:

    This is really strange, i was getting the exact same Realtek HD Audio error, the number was also 0xE0000227.

    I tried a lot of solutions for windows xp sp3 (service pack 3), but only this worked.

    thanks for solving this problem and hd audio on my motherboard is now installed

  3. Harish Says:

    This problem was coming on my computer also, it was saying that driver install failed, and also wasnt even uninstalling the Realtek HD Audio.

    0xE0000227 was really messing up my life, but thanks to the post i solved it.

    it works !

  4. Don Gwinn Says:

    Well, the good news is that Google picked up this post. I found it by Googling “0xE0000227” last night. The bad news is that I’m not tech-savvy enough to pull it off. I don’t know how to do the registry key change you cited, so I tried simply going to Add/Remove Programs in XP and uninstalling Service Pack 3.
    Then I uninstalled the drivers for the audio device (listed as “Unknown Device”) and installed the patch KB88811. It went through and I was feeling pretty smug, but then I tried to install the drivers again and it was right back to “Fail!” and “0xE0000227” again.

    At this point, I’ve put SP3 back and given up. I plan to pick up a PCI sound card today and put that in, but I don’t really like that solution. The new motherboard only has two standard PCI slots, and I’m pretty sure I want to tie one up with extra USB ports.

  5. WiseTechie Says:

    Did u disable UAA in your device manager ?

    right click on my computer icon and click properties.

    Select device manager and disable the UAA.

    Then uninstall the UAA.

    For changing the registry entry, type regedit after using windows key + r.

    Then goto given path and change 300 to 200.

  6. OG Says:

    many thanks man helped in a small bind.

  7. Andrew Says:

    Like the others this error was preventing the HD sound on my Intel board from working. Other sites indicated that this was a SP3 issue, but this is the only one that offered a solution…and it worked.
    Many thanks!

  8. Carl Says:

    Thanks for this, Your fix worked first time. I’ve been trying everything and couldn’t get this driver to install. Worst thing is all that needs to be done is change 1 line in their code to the update the KB888111 patch. to work with sp3. That and the trick to disablle th UAA driver. Thanks again

  9. WiseTechie Says:

    @Andrew and Carl – Both of you are welcome, i had faced this 0xE000027 myself and had spent a lot of time in troubleshooting.Hence i wrote this post.

    Glad to know a large number of people are solving their Realtek HD issues using this post :)

    Hehe , thanks Golddust :)

  19. Kevin Says:

    Great post – battled for an hour before I found it on Google. Maybe for the newbies you should let them know UAA is under sytem devices, and the regedit value need to be in Hex, otherwise, thanx for the time saved.

  20. Brian Says:

    Thanks a lot for this post!

    I was trying to figure out for the past week why I couldn’t install HD audio on my PC. Like you, I tried other sites that had fixes but nothing worked. When I found this post though, I got my sound back!

    I was almost ready to give up because I was so frustrarted with this! Thanks again for the help! This worked like a charm!

  21. AlexD Says:

    Hi, I stack in your fourth step. I can’t uninstall UAA driver from device manager. I it always says: “Failed to uninstall the device. The device may be required to boot up the computer.”
    What to do?

  22. WiseTechie Says:

    @AlexD – before uninstalling, you need to disable the UAA, then uninstall it. Did u disable it ?

  23. Christos Says:

    THANX !!!!
    It works

  24. WiseTechie Says:

    You are welcome Christos :)

  25. Rakesh Says:

    The Realtek 0xE0000227 is indeed a dreaded word for the people who have bought new Intel HD Audio Motherboards, the SP3 error is really something companies should resolve.

    God help those searching for the Realtek 0xE0000227 error to get here :P

  26. Rakesh Says:

    BTW, i too had gotten “Failed to uninstall the device. The device may be required to boot up the computer” error , to get over this, you need to disable the UAA as wisetechie mentioned and then uninstall it.

  27. Takkie Says:

    You powned this error! Thanks to your little guide here,

    After reading many guids, yours finally managed to conquer this nasty error.
    It took me a while to figure out that the UAA was in the “SysteemDevices” trunk and not the unidentified device at “Controls for games etc”.

    Silly me. :-)
    And even more so, stupid Microsoft with their SP3 saying it’s all better, pff. :@

    Thanks a trilion!
    I would like to donate you, so you can keep up with the great work you’re doing. But the paypal button doesn’t seem to work. Email me when you have it working again.

  30. KDee of Garland,Texas Says:

    Thanks for the information, I was having the same problem and you were the only one that was able to fix it. I would like to suggest that you be more detail about the Registry part for alot of people don’t know how to access this area and navigate through it. Metter of fact I had two ControlSet001 and ControlSet002 and I didn’t know which one to go into and change, so I did both.

  31. WiseTechie Says:

    @KDee of Garland – Yeah, probably should, but good thing your Error 0xE0000227 got solved, Realtek should really release a patch with Intel to solve this automatically.

  32. Chris Says:

    Hello all, I’m trying to fix this error. My system devices does not contain UAA. I changed the CSD version to 200 in Hexadecimal, Completed the rest of the steps in the process… minus disabling/uninstalling UAA driver as, like I said it does not seem to exist… Can anybody help???

  33. Harsh Bakshi Says:

    I am trying to install Intel Graphics Media Accelerator Driver for Windows XP from the Intel website (Mobile Intel 915GM/GMS, 910GML Express Chipset Family – RealTEK or Sigmatel Audio)

    The readme.txt says that I need to update my HDMI audio drivers Hdaudiobus.sys using the Microsoft Hotfix – kb888111.

    Can I download the kb888111 patch from websites like sites like softpedia ? Is it safe ?

    Microsoft kb does have a support page with the following information about kb88111 but there’s no link to download the Microsoft audio drivers.

    KB888111 – Universal Audio Architecture (UAA) High Definition Audio class driver version 1.0a available for Windows XP, Windows Server 2003, and Windows 2000

    thanks thanks thanks dude!!!!!!!

  41. Rustee Says:

    Hi and thanks a million!! I’m in Canada (ontario), and have been messing with this problem for some time … and this one WORKED!!!

    I did find on on M$ that for Realtec drivers, the newer downloads have a patch in them that works also. It is the KB888111.exe file that has to be extracted from the MSHDQFE folder (and another click or 2 further into that folder) which shows up when you double click the driver folder. Just click on folders that match your computer (like XP or Vista or Win2000 etc.) I eventually came to a folder that was marked us … and clicking on that folder revealed 3 different fixes … I used KB888111xpsp2.exe from the downloaded Realtec Driver folder and it worked just fine.

    Thanks again for the GREAT info for this problem …


  42. Brian Dickens Says:

    Thanks for the solution to this annoying problem! I work at a helpdesk and one of our clients had problems with his soundcard. When I tried to install the most recent Realtek HD audio drivers, I got this exact same error.

    Thanks to Google I found this solution in just ten seconds and it worked!

    I’ve bookmarked this page, I’m sure in the future I’ll be needing it again :)

  43. WiseTechie Says:

    @everyone who thanked – you guys are all welcome, I am glad people around the world are being helped by what I wrote.

  44. jonathan smith Says:

    my windows folder only has these

    and things that don’t seem important

    is SP200 the same as service pack 2? can i just remove service pack 3 and install service pack 2 and then reinstall service pack 3 as the last step?

  45. jonathan smith Says:


    Thanks so much!! It actually works, although the steps were kinda hard to figure out, or maybe I’m just stupid. Regardless.. thanks a lot!

  46. Maddy Says:

    Tnx, your post is very good.

  47. Mohsen Says:

    thanks alot , i have really suffered past two years everytime i install os and i keep installing and unsintalling things till it works and i never knew how and why it got solved …. now i got it in a glimpse

  48. bruce Says:

    i’m not sure what to do. is it right to disable “Microsoft UAA bus driver for high definition audio” from SYSTEM DEVICES in device manager?

    because when i try to disable this it says that disabling this device will cause it NOT to function.

    i’m afraid i might cause damage in my computer. i just wonder if “Microsoft UAA bus driver for high definition audio” is still the same UAA.
    sorry I doesn’t really know much about computers.

  49. bruce Says:

    I’ve tried it and it doesn’t work on me. :(

  50. Rohit Says:

    “Cause it not to function” simply means that it won’t work until you have enabled it again. It won’t damage your device in any way at all.

  51. Taivan, from Mongolia Says:

    Really thanks, it helped me, now my sound is no problem.

  52. Gabo Says:

    Go to Device Manager/Device Drivers

    Disable microsoft UAA bus driver …

    Try to Uninstall UAA bus driver…i cannot, reboot then uninstall. If u get install

    new hardware wizard after reboot cancel it.

    Unistalll ANY sound device u had before (sound card or onboard chip)

    Reboot… cancel new hardware wizard….

    Install realtek driver and it will work…after Realtek sound is working,

    reboot…accept new harware wizard, it will then install UAA bus driver again,

    and everything will work just fine!!!

  53. Iron Maiden 1200 Says:

    Thank you. Thank you. Thank you. I just went through 24 hours of Windows hell. Only to have this happy little turd surprise waiting for me upon the OS reinstall. Worked like a charm. Keep on posting!

  54. Martin Says:

    Dear all friends, i am also facing the same problem, but i can’t find the UAA in device manager pls advise how to find that in device manager.

  55. Hizab Says:

    Wow! Now that was cool. I had Windows xp sp2 installed on my computer. But, upon installing drivers I too came across the same problem of sound. So, i googled the problem and found this tech blog. I did as said. Note here that the above solution works for Win xp sp2. I didn’t have that much trouble. For those of you who don’t know where to find hklm i.e. that above link, here’s the solution. Just go to the run command in the start menu and type regedit. HKLM stands for ‘HKEY_LOCAL_MACHINE’. Then you will be able to find where to change the csd version by going according to the link. Sometimes for ControlSet it will be ControlSet001. Choose that. Then go as per the instructions given above. Choose to download the KB888111 patch from cnet.com because it’s safe. In device manager UAA will be found under System devices. If it is not present, continue with the installation else disable and uninstall it. Proceed as above. Upon installing the KB888111 patch itself upon restarting the sounds will come.
    Next install the realtek drivers. You’re then up in no time.

    Wishing you happy computing!

  56. PJ Omnath Says:

    The solution given is excellent. It solved the hectic problem of my audio driver. Thanks for the solution. I disabled, uninstalled Microsoft UAA from device manager. Then realtek was installed. Then rebboted ths system. When it prompted for the messgae of ‘some updates will be done if not restarted’ rebboted my system. I could hear sound. Excellent approach!!!!!

    Hi From South Africa (XP SP3)
    After going through the sequence (CSDVersion 300 to 200 etc), I have lost the ability to execute .exe files. I found (but cannot find again) a comment that stated that after the install sequence if drivers dont load, then there is a hotfix.. Would you know what this hotfix is and where I could find it? Thanks.
